This invention relates to a novel and useful combined paint applicatorand handle pump and more specifically to a paint applicator of the brushtype and including a handle portion with the brush portion thereofincluding a flexible paint reservoir enclosed Within the brush bristlesthereof.

The paint applicator of the instant invention may or may not be providedwith a paint pump in the handle portion thereof but is, in allinstances, provided with a paint reservoir enclosed within the bristlesand paint conduit means communicated with the paint reservoir at one endand adapted for communication with a suitable source of paint supply atthe other end. The handle portion of the paint applicator may include ahand actuated pump or may be devoid of a pump in which instance thepaint conduit extending to the paint reservoir may be communicated witha supply of paint under pressure at its inlet end.

In addition to the above mentioned components, the handle portion of thepaint applicator remote from the brush portion may be provided with amounting coupling for removable securernent to one end of an elongatedtubular handle. Should the paint applicator be provided with such atubular handle, the paint conduit of the applicator may extend throughthe tubular handle to the aforementioned source of paint.

A main object of this invention is to provide a paint applicatorincluding means whereby a supply of paint from a source thereof may becontinuously delivered to the paint applicator thereby eliminating thenecessity of a painter having to intermittently stop his work in orderto replenish the supply of paint on the applicator.

A further object of this invention, in accordance with the immediatelypreceding object, is to provide a paint applicator including a handleportion having a paint pump mounted thereon for pumping paint from asource of paint to the appl-icating portion of the pain-t applicatorwhereby a painter using the paint applicator may continuously controlthe amount of paint being delivered to the applicator portion of thepaint applicator.

Another object of this invention is to provide a combined handle-typepaint pump constructed in a manner whereby it may be readily adapted foruse in connection with various types of paint applicators.

A final object of this invention to be specifically enumerated herein isto provide a combined paint pump applicator and handle pump which willconform to conventional forms of manufacture, be of simple constructionand easy to use so as to provide a device that will be economicallyfeasible, long lasting .and relatively trouble-free in operation.

These together with other obje ts and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIGURE 5 is a fragmentary longitudinal vertical sectional view takensubstantially upon a plane passing through the longitudinal center lineof the hand pump illustrated in FIGURE 4; and

FIGURE 6 is a vertical transverse sectional view taken substantiallyupon the plane indicated by section line 66 of FIGURE 5.

Referring now more specifically to the drawings, the paint applicator ofthe instant invention is generally referred to by the reference numeral124 and includes a handle portion 126 .and a brush head portion 128.

The brush head portion 128 includes a plurality of brush bristles 130similar to those provided on conventional types of brushes and disposedwithin the bristles 1 30 is a flexible and apertured pancake-likebladder reservoir generally referred to by the reference numeral 132.The reservoir 132 includes an inlet neck portion 1-34 and it may beobserved from FIGURE 2 of the drawings that the handle portion 126includes a longitudinal bore 136 through which the end of a flexibleconduit 60 extends.

The outlet end of the flexible conduit 60 is secured to the inlet neckportion 134 in any convenient manner and it will be noted that amounting coupling generally referred to by the reference numeral 138 isalso provided for the handle portion 126 and that the mounting coupling138 includes a cylindrical portion 140 provided with J-shaped slots 142,The end or" an elongated tubular handle (not shown) may be telescopedwithin the cylindrical portion 140 and be provided with laterallyoutwardly projecting projections releasably securable in the J-shapedslots 1'42 whereby a bayonet type connection between the cylindricalportion 140 and the associated tubular handle (not shown) may be formed.Additionally, it may be observed from FIGURE 2 of the drawings that themounting coupling 13% is removably secured to the handle portion 1-26 bymeans of spring urged detent elements 144 carried by a slide 146 whichis clampingly secured to mounting coupling 13 8 by means of spring arms.148 and 151 formed integrally with the cylindrical portion 140.

The end of the flexible conduit 613 remote from the inlet neck portion134 may be adapted for communication with any suitable supply of paint.Such a supply of paint maybe under pressure so as to continuously supplypaint to the reservoir 132. Additionally, a control valve (not shown)may .be disposed in the flexible conduit 60 intermediate its inlet andoutlet ends for controlling the flow of paint therethrough to thereservoir 132.

With attention now directed to FIGURES 4-6 of the drawings there will beseen a modified form of brush type applicator generally referred to bythe reference numeral 152. The brush-like applicator 152 also includes apancake-like bladder reservoir 154 similar to the reservoir 132 and itwill be noted that the handle portion of the applicator .152. isgenerally referred to by the reference numeral Patented Aug. 3, 1965 156and comprises a hand pump. The hand pump 156 includes a pair of halfhandle portions 153 and 160 which are secured together by means offasteners 161. The hand pump 155 has a reciprocal piston sleeve 162mounted therein for reciproca-ble movement in the end of the flexibleconduit 164 which corresponds to the flexible conduit 6%. A flap-typevalve 166 is disposed in the inl t end of the piston sleeve 152 andopens to admit paint into the piston sleeve 162 upon movement of thepiston sleeve to the left as viewed in FIGURE 5. Then, upon return ofthe piston sleeve 162 to the right as viewed in FIGURE 5, the flap valve.166 will close and thus force a portion of the paint disposed thereinoutwardly of the outlet 168 of the hand pump 156 which is incommunication with the interior of the reservoir 154.

A movable actuator lever 170 is pivotally mounted between the two halvesS and 168 by means of a pivot pin 172 and the piston sleeve 162 includesa laterally projecting arm 173 which is spring urged to the right asviewed in FIGURE 5 by means of a compression spring 174 disposed betweenthe pivot pin 1'72 and the arm 173.

A pair of levers 176 are secured to the movable actuator 179 by means ofpivot pin 17S and have journalled between their free ends a roller 189by means of a pivot pin 182. The roller 18!? is disposed in rollingcontacting relation with an abutment surface 184. A pair of levers 186are each pivotally secured at one end to the pivot pin 182 and have aroller 188 rotatably supported between the opposite ends by means of apivot pin 1%. The roller 188 is disposed in rolling contacting relationwith the abutment surface 192 and in contact with the laterfllyprojecting arm 173 of the piston sleeve 162. Thus, upon depression ofthe free end of the movable actuator 170, the linkage formed by thelever 17% and 186 will be extended in order to move the arm 173 to theleft as viewed in FIGURE 5. Accordingly, paint may be pumped through theflexible conduit 164 and into the reservoir 154 by actuation of themovable actuator 170.

Thus it may be seen that the hand pump 156 may be utilized to pump paintinto the reservoir 154. However, it is to be noted that the applicator152 is to be used in conjunction with a suitable supply of paint withwhich the inletend of the flexible conduit 164 is in communication.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.
